Heteropolysaccharides:

Definition: Heteropolysaccharides are complex carbohydrates composed of repeating units of two or more different types of monosaccharides, linked together by glycosidic bonds.

 

Types:

   • Examples: Found in the exoskeletons of arthropods, cell walls of fungi, and some insects.
   • Sources: Arthropods, fungi.
   • Location: Predominantly present in the exoskeletons of arthropods, providing structural support.

2. Hyaluronic Acid:

   • Definition: A linear, non-sulfated glycosaminoglycan and heteropolysaccharide.
   • Structure: Repeating units of N-acetylglucosamine and glucuronic acid.
   • Examples: Synthesized by the body, used in cosmetics.
   • Sources: Synthesized by various cells in the body.
   • Location: Abundant in connective tissues, synovial fluid, and skin, contributing to lubrication and hydration.

3. Pectin:

   • Definition: A heteropolysaccharide found in the cell walls of plants.
   • Structure: Composed of galacturonic acid, arabinose, and other monosaccharides.
   • Examples: Found in fruits, acts as a gelling agent in jams and jellies.
   • Sources: Citrus fruits, apples, berries.
   • Location: Mainly present in the primary cell walls of plant tissues, contributing to their structure.

4. Hemicellulose:

   • Examples: Found in plant cell walls, providing structural support.
   • Sources: Wood, plant cell walls.
   • Location: Abundant in the secondary cell walls of plant tissues, contributing to their strength and flexibility.

5. Agar:

   • Definition: A heteropolysaccharide extracted from certain red algae.
   • Structure: Composed of alternating units of agarose and agaropectin.
   • Examples: Used as a solidifying agent in culture media and in the food industry.
   • Sources: Red algae.
   • Location: Extracted from the cell walls of red algae, commonly found in marine environments.
   • Composition:
     • Agarose: Typically comprises about 70-80% of agar.
     • Agaropectin: Makes up the remaining 20-30% and contributes to the branched structure of agar.

Agarose and Agaropectin:

• Agarose:

  • Definition: A linear polymer within agar, composed of repeating units of agarobiose.
  • Structure: Forms the backbone of agar, contributing to its gel-forming properties.
  • Function: Primarily responsible for the solidifying nature of agar in culture media and other applications.

• Agaropectin:

  • Definition: A branched polymer within agar, consisting of various monosaccharides.
  • Structure: Side chains branching off from the agarose backbone.
  • Function: Provides additional complexity to the structure of agar, influencing its overall properties.
